Electronic leak detection in Blackbrook

How we price electronic leak detection

The price reflects the time and kit the roof needs. That comes down to:

  • Extra roofs, like extensions, dormers or garages
  • Roof area
  • Features like valleys, chimneys, dormers and parapets
  • Whether thermal imaging or a drone is needed

To find out what your survey will cost, call 07833 053749 or use the contact form with the address and some details. We will confirm the figure before booking.

Getting in touch

These details help when you contact us:

  • Where water is showing inside, if it is

  • The reason for the survey, like buying, a leak or storm damage

Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or use the contact form with the address and the days you’d prefer.

How electronic leak detection works in Blackbrook

ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We will tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. We will point you to the likely next step. If you’ve noticed damage from equipment installers and breaches hidden under paving or planting, a survey will tell you what’s going on, whatever the roof.

Flat roofs on exposed homes in small places like Blackbrook take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.

Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

Blackbrook: your questions answered

Do you cover smaller places like Blackbrook?

We do. A small place gets exactly the same survey as a big one.

Is my home in Blackbrook listed or in a conservation area?

Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.

Is this an asbestos survey?

No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.

Can you inspect my roof with a drone?

Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.

How much does electronic leak detection cost?

We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or send us an email for a quote.

Is it the same as a RICS Level 2 or Level 3 survey?

No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.

Can every flat roof be tested?

It depends on the membrane and the build-up. Tell us what you know about the roof and we’ll check whether ELD will work.

Can I check my roof myself?

Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.

Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.

The survey, step by step

Once we have finished looking, we write up our findings as a report with photographs, emailed to you. As for time on site, most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Blackbrook can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.

  1. First, you let us know about the roof build-up and where water is showing.
  2. We confirm whether the roof is suitable for electronic testing.
  3. The testing method is chosen to suit the membrane and build-up.
  4. The roof is tested and any breaches are located.
  5. You get a report showing where each breach is, for your roofer to repair.

Tips that help

There is plenty you can do without going near the roof. Here’s what helps most:

  • Limit access to the roof
  • Do not keep patching the same spot
  • Keep outlets clear of debris
  • Act on new leaks promptly

After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.

Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.

Electronic leak detection in Blackbrook: local notes

Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Blackbrook has a long history of building, with Polesden Lacey about 4.3 miles north-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.

For site and facilities teams at buildings like St John's Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to Church of St John the Evangelist: the joins between later flat roofs and the old walls are where problems normally start. If you own a rental within reach of Holmwood station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What this survey can’t tell you

No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:

  • Fixing the holes we find
  • Build-ups without a suitable layer below
  • Sections we cannot safely access

If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. What a survey covers and doesn’t.
